The new Siux Electra Stupa Pro ST4, Franco Stupaczuk's official racket for the 2025 season, is now available. This high-performance model is designed for players who dominate the court and seek a perfect combination of power, precision, and spin.

Its hybrid format and medium balance offer a balanced and versatile response, providing outstanding performance in both defense and attack.

The 15K carbon faces provide exceptional durability and explosive ball speed on every shot, while the 3K carbon frame reinforces the structure without adding extra weight. Its EVA Hard rubber offers a firm and energetic feel, ideal for players seeking speed and aggression without sacrificing control.

The glossy, sandy finish enhances ball grip, boosting spin on lobs, volleys, and smashes. It also features the innovative Switch Strap system, allowing you to swap out the grip strap for greater comfort and hygiene.
